DS18B20-MS 产品概述

一、产品简介

DS18B20-MS(品牌:MSKSEMI / 美森科)是一款基于单总线数字温度测量的半导体温度传感器,采用TO-92封装,适合嵌入式系统、工业控制、家电及环境监测等多种应用场景。器件以数字形式输出温度数据,简化了与单片机或微控制器的接口设计,便于批量并联和远距离布线。

二、主要规格

  • 温度测量范围:-55℃ ~ +125℃
  • 精度:±0.4℃(典型/参考)
  • 温度分辨率:12 bit(可获得最大分辨率)
  • 单次温度转换时间:400 ms(12-bit 分辨率)
  • 接口类型:单总线(1-Wire)
  • 工作电压:2.5 V ~ 5.5 V
  • 待机电流:约 1 μA
  • 封装形式:TO-92
  • 品牌:MSKSEMI(美森科)

三、关键特性

  • 高精度与高分辨率:12-bit 分辨率配合±0.4℃的精度,能满足大多数温度检测与控制场合对精确度的需求。
  • 低功耗:待机电流约 1 μA,适合电池供电或低功耗在线监测系统。
  • 宽电源范围:2.5 V ~ 5.5 V 的工作电压使其兼容多种微控制器电平与系统供电设计。
  • 简单的单总线通讯:采用单总线接口,节省I/O资源,支持一线多点连接,便于扩展多个温度节点。
  • 快速转换:在12-bit 分辨率下,典型转换时间为400 ms,适合绝大多数中低速监控场景。

四、典型应用

  • 工业设备温度检测与过温保护
  • HVAC(空调/暖通)系统温度监控
  • 家用电器(冰箱、热水器等)温度控制
  • 数据中心与服务器机柜温度检测
  • 环境监测与物联网节点(结合低功耗通信)
  • 电池管理系统与充电设备温度监测

五、使用建议与注意事项

  • 接线与上拉:单总线数据线通常需要一个上拉电阻(常见值 4.7 kΩ),以保证总线空闲时为高电平。若采用寄生供电模式,请参考具体应用对电源与时序的要求。
  • 去耦与抗干扰:在噪声环境中建议在电源侧加适当去耦电容,并在数据线上考虑增加ESD保护或滤波以提高可靠性。
  • 散热与布局:TO-92 封装的热响应与环境散热相关,传感器应尽量与被测对象热耦合同时避免热源干扰。需要快速响应时缩短导线并减少热阻。
  • 校准与容差:虽然器件精度优良,但在对精确度有严格要求的系统中,建议进行少量点校准或在固件中加入温度补偿算法。
  • 多点布线:单总线允许多个器件并联,但要保证总线上每个节点的地址唯一并注意总线长度带来的时序与衰减影响。

六、封装与采购信息

DS18B20-MS 提供标准 TO-92 封装,便于手工焊接与快速原型开发,也适合批量插件式装配。购买与选型时请确认供货商提供的完整数据手册以便获取详细的电气参数、引脚定义、通信时序与应用电路等信息。

结语:DS18B20-MS 凭借其数字输出、宽电压范围、低功耗与高精度特性,是一种通用型温度传感解决方案,适合各类电气与电子系统中的温度检测与控制任务。若需与特定平台或总线拓扑集成,可提供更详细的接线与固件实现建议。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
